Release Notes: Besides being an update to the 2.4.37.3 kernel release, this revision of the patch introduces an additional security hardening measure where the kernel would no longer allow the "personality" feature (which is needed to support some program binaries from other operating systems) to be abused to bypass the vm.mmap_min_addr restriction via SUID-root programs with a certain class of design errors in them.

Release Notes: This release was updated to Linux 2.4.37.1. Functionality of the CONFIG_HARDEN_PAGE0 feature has been revised to apply on top of the vm.mmap_min_addr sysctl introduced in mainstream 2.4 kernels, and the documentation has been revised accordingly.

Release Notes: This revision adds a fix for the "parent process death signal" vulnerability in the Linux kernel. It also adds two security hardening features, both enabled by default: restricted access to VM86 mode (specific to 32-bit x86) and restricted zero page mappings (generic).
